The Cisco Long-Reach Ethernet solution meets the demands of high bandwidth applications while leveraging the existing copper wiring infrastructures. Catalyst® 2950 Long-Reach Ethernet (LRE) Series switches enables enterprise and service provider customers to extend intelligent services over existing phone and legacy wiring to distances up to 5000 feet. Cisco is the only company with the breadth of technologies that allow customers to deliver intelligent network services across any combination of wired and wireless infrastructures.
Each LRE link is terminated with either the Cisco 575 or 585 LRE Customer Premise Equipment (CPE). Both CPEs are fully compatible with the Catalyst 2900 LRE XL and Catalyst 2950 LRE Series switches. Please refer to the Cisco Catalyst 2950 LRE, Cisco Catalyst 2900 LRE XL and Cisco LRE POTS Splitter data sheets for more information.
These compact devices bridge LRE and Ethernet, and provide one (575) or four (585) RJ-45 switched Ethernet connections and two RJ-11 connectors—one for the wall and one for a telephone. The Cisco LRE CPEs can be mounted on or under a desk, or on a wall. It ships with a mount lock-in mechanism and clip-on Ethernet cable guard to discourage theft, as well as an Ethernet cord (575 only). The Cisco LRE CPEs device supports POTS traffic—including ISDN or digital phones—that coexists over the same LRE line by splitting LRE and POTS traffic at the CPE device. A POTS Splitter is required for connectivity to the PBX and LRE switch stack.
The Cisco 575 and 585 LRE CPEs are managed remotely through Command Line Interface (CLI) on the LRE switches or through Cluster Management Suite (CMS). Ethernet statistics and Remote Monitoring (RMON) support are available from the switch for both CPEs. CPE Ethernet port configuration is readable via SNMP. The speed and duplex of the Fast Ethernet ports on the CPEs are configurable with the speed and duplex defaults set to auto-negotiate and half respectively. Both CPEs pass though 802.1Q tags but do not perform any tagging. The Cisco 575 and 585 LRE CPEs are hot-swappable without powering down the switch or disrupting the other switch ports. Customers cannot link two LRE CPEs back-to-back. Each LRE CPE must connect to an LRE switch port.
Cisco 575 LRE CPE Device
The Cisco 575 LRE CPE is a simple one-port bridge that translates LRE into Ethernet. The Cisco 575 CPE has one Fast Ethernet port and two RJ-11 connectors: one for the analog phone and one for the LRE link.
